Tekken2 + lr-pcsx-rearmed = vertex explosions

pxi

Hello all, this is my first post here. :-)

Last Friday I ran a full update of a Retropie running on a pi4. This updated several emulators, among them lr-pcsx-rearmed.

The problem is that now my Tekken 2 ROM has distorted graphics similar to the ones on this post on reddit. The OP there solved the problem by reinstalling everything, but I think a simple downgrade of lr-pcsx-rearmed could do the trick?

I've checked and there are no other emulators for PSX available for armv7. PCSX ReARMed and lr-beetle-psx complain about incompatible tags and lr-duckstation is nowhere to be found in the package lists.

Any help on the subject is greatly appreciated.

i can confirm this issue.

I find a working version that looks that is working with the game. To downgrade follow this steps :

From the terminal run this command :

sudo nano /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-pcsx-rearmed.sh

change the line :

rp_module_repo="git https://github.com/libretro/pcsx_rearmed.git master"

to be :

rp_module_repo="git https://github.com/libretro/pcsx_rearmed.git master e007af2"

then press Ctrl+O and Ctrl+X to save the change to the file.

In the end choose, to install the packages from source .

For lr-duckstation you have to install it manually because it is removed from RetroPie.

From my personal back-up, you can download the lr-duckstation package and install it, instructions:

Downoad the zip file from here( after 24 hours, the link it will expred) : https://easyupload.io/gmyq1e / unzip it.
Put the folder lr-duckstation here :

/opt/retropie/libretrocores

Put the lr-duckstation.sh here :

/home/pi/RetroPie-Setup/scriptmodules/libretrocores

From the terminal run :

cd $HOME/RetroPie-Setup

sudo ./retropie_packages.sh lr-duckstation configure

You are ready. You can delete the lr-duckstation.sh to not have the error messages during the updates.

It may also be helpful to file a bug report here: https://github.com/libretro/pcsx_rearmed/issues

Since it looks like the emulator has been getting more updates recently, hopefully it can be fixed.

@windg thanks so much for your help!

I've installed lr-duckstation and it works like a charm. I also ran the downgrade of lr-pcsx-rearmed, but so far no luck.

[EDIT: I'm an idiot, I forgot to compile it from source. On a side note my controls have been reset, all though my saves still work.]

As @quicksilver suggested I've copied and edited version of this post on their issues tracker here. And hopefully I can assist them if they need more information to fix the bug.

Thank you again for your help :-)

@pxi You can add a verbose log to the issue - toggle debugging from the Runcommand menu and you'll be able to get a verbose log. This should help to confirm there's no other issue involved (wrong BIOS, image, etc.).

@mitu I've asked them if it would make the situation clearer, and I'll revert the changes to provide a log if they request it.

~~Out of curiosity I tested Tekken 3 (I don't have Tekken 2) and I did not experience this issue. Do you have Tekken 3? If so could you test to see if it has the same issue for you?~~

Scratch that looks like there should be a fix now: https://github.com/libretro/pcsx_rearmed/issues/613

You should just need to restore your script module to original version and update from source to get it.
